I should have further asked then: How, do you get an LT4 (ZL1) that you put a CAM in to increase the inlet side? Pulleys, a 2650? The reason I'm asking, when I was looking at a CAM when I first got my ZL1. A buddy showed me his data logs of before and after and I was surprised to see the boost drop after he put a CAM in. He gave me some kind of BS reason why, but I could tell he didn't really know. This is one reason I'm still on the fence about a CAM myself. I think the original poster might not realize a CAM will lower boost, unless they do other mods?
